You're only going to get advice to snowboard here

but seriously, while the first 2 days on a board will be much harder than the first 2 on skis, you will enjoy boarding more than skiing immediately after that. Skiing has a long slow learning curve - you just keep on learning. Whereas as boarding has a short steep learning curve - it's starts out impossible, and then seems easy.
I hadn't skiied, surfed, skateboarded or anything when I started. (Tho I had done lots of motorcycling & MTBing). And I was over 30. The bench mark I use is that at the end of your first week you should be comfortable doing blue runs.
I have no experience of these, but I would recommend some lessons in the UK. Every hour spent falling over here is an hour you won't have to spend in the resort. Learning on a dry-slope is hard (and painful), but it does teach you good technique.
